Product Description
4W7031 Cat-erpillar Direct Injection Fuel Injector
The 4W7031 fuel injector is an original direct injection assembly specially engineered for Cat-erpillar diesel engines, delivering precise fuel atomization and stable fuel delivery to support efficient combustion. Adopting mature mechanical direct injection structure, it features high sealing performance, strong pressure resistance and excellent wear resistance under long-time high-load operation.
Strictly manufactured to OEM dimensional specifications, this injector effectively controls fuel injection volume, injection timing and spray angle, reducing incomplete combustion, black smoke emission and fuel consumption. It is applicable to matched Cat-erpillar industrial engines, construction machinery and generator sets, solving issues like weak power output, rough idling, hard starting and excessive exhaust smoke caused by faulty injectors.
Made of premium alloy materials with precise internal component matching, it boasts long service life, easy installation and reliable consistency after replacement, meeting rigorous working demands of heavy-duty engineering vehicles and stationary diesel equipment in harsh workingenvironments.
Applicable equipment: Cat 980C wheel loader, D8 series bulldozer, marine propulsion engines and stationary generator units matched with 3406 powerplant.
Cross interchange part numbers: Compatible with 0R series equivalent reman injectors, interchangeable with matched 4W series pencil injectors for 3400 family engines, direct drop-in replacement without modification.
